OIL-BURNER.

Specification of Letters Patent.

Patented Apr. o, 191s.

Application filled December 31, 1917. Serial No. 209,679.

To all whom it may concern:

Be it known that I, CHARLES A. JAPHET,

. cause a perfect combustion thereof.

The primary object is to provide a device of simple construction for heating purposes, wherein a fuel oil, such as one of the lighter hydrocarbon oils like kerosene, distillate,

etc., may be used, and which, in the operation of the device, consumes all the carbon, and therefore eliminates soot and smoke, and causes the oil-gas to burn with a bluewhite,4 transparent flame, generating the maximum amount of heat with a minimum consumption of fuel.

Another object is to provide a device of 'this' character which 4is composed of .few

parts, comprising simple castings and pipe fittings, the same being capable of manufacture at a low cost, and may be readily installed in stoves, ranges, furnaces, or other tire boxes, where it is desired to utilize fuel oil for the generation of heat.

A further object is to construct a device of this class which has means for ready access in order to ignite a small quantity of fuel oil upon the initial heating of the parts,

' which is necessary in such burners, for the purpose of converting the said oil into gas, and'to arrange theparts into compact form in order to prevent breakage of the same in shipping, -and to facilitate'the installation of the burner.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification, it being understood that while the drawing shows practical forms of the invention,`thel latter is not confined to strict y conformity therewith, but may be changed or modified, so long as such changes or modifications mark no material departure fromthe salient features of the invention, as specifically pointed out in the clalms appended hereto.

In the drawing, in which like reference characters designate like parts throughout the several iguresz- Figure 1 is a vertical longitudinal sectional view of the improved burner;

Fig. 2 is a top plan View thereof, partly broken away Fig. 3 is a bottom plan view of the same;

Fig. 4 is a side elevation, taken at right angles to Fig. 1.

Referring to the drawing, the invention comprises an air duct 1 of tubular form, preferably roundin cross section, and open at each end. This tubular air duct 1 is arranged vertically when the .device is inthe installed position within a fire box, and is formed by casting from any suitable metal capable of withstanding the intense heat to which the burner is subjected.

The air duct 1 is provided with a surrounding annular channel or gutter 2 cast integrally therewith and located at the upper portion of the air conductor l. The bottom of the channel or gutter 2 is located substantially midway of the height thereof, and the upper edge of the outer wall 3 df the channel 2 terminates short of the upper edge of the air duct, and is there provided with a flat, annular, outstanding wall 4, having its peripheral edge provided with. an

the air duct 1, thus defining a pan of approximately twice the diameter of the central air duct 1. l

Beneath the bottom wall 4 of the pan there is provided a pair of diametrically opposite enlargements or bosses 6, formed integrally therewith and connected with the outer wall of the air duct 1, the bottom faces of the bosses extending out on a level with the bottom wall of the channel or gutter 2 which is preferably rounded on the inside as shown.

As far as described, the parts are ,all formed in a single casting of compact circular formation, in plan view, having no projecting parts, thus facilitating the handling thereof when installing the burner within the fire box of a stove, etc.

The diametrically opposed enlargements or bosses 6 are bored longitudinally through- 'upstanding marginal flange 5, the top edgev of which .is on a level with the top edge of.

llt)

nular channel or gutter 2 and near the rounded bottom thereof. r1`he outer ends of the ducts are threaded for the reception Vof, threaded closure plugs 8 which are tapped 4into place, this being found to bethe.easiest way to cast the device and having the added advantage of being readily removable, should it become necessary to clean out the passages or' ducts 7. y

ySubstantially midway of the lengths of the bosses 6, vertically disposed counterbores 9 are provided through the bottoms thereof which intersect the ducts 7 and are threaded as by a left-hand thread to receive the upper appropriately threaded ends of similar nipples 10, which are somewhat less in length than that portion of the air duct 1 extending below the bottoms of the bosses 6, for a purpose to be described. l. y

The lower ends of the said nipples are provided with right-hand threads to connect one with an elbow 11 and the other with a "il" -coupling 12, which are in turn threaded for a pipe connection 13, which is clit'the proper length to engage the elbow and coupling 11 and 12 respectively, and lies in a horizontal plane below and across the lower end of the air duct 1.

rlthe bottom circular edge of the cylindrical air duct 1 is provided with diametricaliy opposite grooves 14 arranged in alinement with the ducts 7`in the bosses 6, and are adapted to form seats for the pipe connection 13, after the same has been brought into seating position therein by properly turning the nipples 10, having the oppositely threaded connections at their upper and lower ends as will be clearly understood.

By this arrangement the pipe 13 is rigidly braced in its connection with the main i casting, and danger of dislodgment or breakage in shipping` or handling is reduced to a minimum.

A feed pipe 15 is suitably threaded into the remaining connection of the T-coupling 12, and is adapted to connect with a source of supply (not shown) such as a tank or reservoir having suitable valve cont-rol for the dow of the fuel oil, it being understood that the said tank or reservoir is located in a somewhat elevated position so as to insure a steady flow of fuel through gravity.

A circular deiector plate or spreader 1G is to be used in conjunction with the above described device, and is provided with a plurality of supporting lugs 17 having' downwardly projecting inner portions 18 arranged to fit within the upper end of `the air duct 1, when the said lugs 17 .are resting upon the upper edge thereof, to prevent any lateral movement of the Spreader 16 while the latter is supported in spaced relation to said duct 1 and the above mentioned pan. The spreader. 16 is of a diameter somewhat less than the diameter of Said pan, and is provided upon its upper side with a centrally located ring 19 suitably secured thereto and forming anger-hold for placing the spreader in positionfasshown and described, or in removingthe same `therefrom when it is desired to light the fuel same when starting a fire.

'llhe burner when properly assembled 1s adapted to be setup and supported within the fire box of a stove, range,'orheater in any `desired manner, an excellentmetho'd having been found in supporting the main casting upon a pair of bricks arranged parallel with the feed pipe of the burner, after the grate of the said re boX has been removed. By arranging the bricks in this manner upon the bottom of the ash pan and spacing the bricks far enough apart to provide ample air passageway therebetween to the air duct 1, the top'of the burner will be in proper position within the fire pot, and the feed pipe 15 will be properly positioned to enter through the front of the ash pit or otherwise.

When it is desired to start the fire, it is only -necessary to open the valve (not shown) slightly to permit a small quantity of fuel to enter the oil channel or gutter 2 through the nipples 10 and the ducts 7 when t e same will flood the nails or other metal bits 20, and, by being separated into many parts, becomes readily ignitible. By removing the spreader 16, easy access is gained in order to ignite the oil, when the said spreader is replaced and the oil, in burning, heats the adjacent parts, including the spreader. An upwardly directed current of air is thus caused to rise throughthe air duct 1 and flows outwardly, in a radial manner, by coming into contact with the spreader acting as a deflecting plate and passes over the burning oil, carrying the flames therewith, to the annular space between the lower marginal edge of the spreader and the annular upstanding rim or flange 5 of the pan. When the parts become suiiciently heated, the infiowing fuel, by being subjected to this lateral blast of ar, is converted into gas which burns freely, around the edge of the spreader, in a blue flame giving forth intense heat, as has been demonstrated in practice.

. From the foregoing, it will be seen that an extremely simple burner has been designed for 'the use of fuel oils which is capable of being readily installed in a re bo-X of any stove, range or other heater, and the operation thereof is exceedingly simple, thus reducing to a minimum the danger usually attendant upon such heaters.

What is claimed is 1. An oil burner compr-ising a central vertically disposed tubular air duct open at each end, an annular oil channel provided on the outside and near the top, thereof, the outer wall of said channel being connected to an annular horizontally disposed wall which is on a higher plane than the channel and is provided with a marginal upstanding liange, said wall and flange forming a pan,-

diametrically opposite bosses formed on the outer channel wall and the underside of the horizontal wall and having lateral bores communicating with the said channel, plugs for closing said bores, vertical counterbores lead- 2. An oil burner comprising a vertically disposed tubular air duct, having opposite notches 1n its lower end, an annular oil channel formed on and surrounding the said duct near the top thereof, said channel having its outer wall provided at its top with a horizontally disposed annular wall having a peripheral upstanding flange, said horizontal thereto, diametrically opposed bosses formed beneath the horizontal wall and having lateral bores with closure plugs at their outer ends and communicating with the oil channel, .vertical counterboresl communicating with the lateral bores, downwardly extending nipples extending from the counterbores, and a feed pipe connecting the lower ends of the nipples and extending across and seated in the said notches lin the 'lower end of the air duct, the air duct, channel, annular wall,

flange and bosses being formed in a single casting. i

ln testimony, that I cla-im the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
